How it works
Spreadsheet times are fractions of a day, so dividing hours by 24 turns 7.75 hours into 0.3229 of a day. With the h:mm number format, that shows as 7:45. The 0.2 hour in 8.2 is 12 minutes.

In Google Sheets
The same formula works in Google Sheets: =B2/24. We ran it in Google Sheets mode on the same data and it returns the same results.
Other ways to do it
Each one was run on the same example sheet.
| Formula | Result | When to use it |
|---|---|---|
| =TEXT(B2/24,"h:mm") | 7:45, 1:30, 0:15…Different result | Text like 7:45, for labels. Text. |
| =INT(B2)&":"&TEXT(MOD(B2,1)*60,"00") | 7:45, 1:30, 0:15…Different result | Builds the text from whole hours and minutes, and keeps counting past 24 hours. Text. |
Common mistakes
- Without a time format the result shows as 0.3229. Format the cells as
h:mm. - With h:mm, totals of 24 hours or more wrap around. Use the custom format
[h]:mmfor durations that can pass 24 hours.
Try it yourself
Same data, empty answer cell. Your formula is graded instantly, then re-checked on changed data, so a typed-in number won't pass.
